Not the exact same but we have a file for ensuring everybody is appropriately up-to-date on local keys people keep on their own machine for development. On boot, if you're not in sync the app is going to tell you. This means you literally can't ignore the issue.
Could you implement some system within the code that forces people to keep up to date?
I like this, I see it a bit bureaucratic but maybe we can find a balance.
We’re a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
